[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a composite roof photovoltaic system, comprising a plurality of photovoltaic subsystems arranged on a color steel tile roof 6, wherein the plurality of photovoltaic subsystems are arranged in multiple rows and columns; each photovoltaic subsystem comprises a composite support rail 2, wherein the number of the composite support rails 2 is at least one, and when the number of the composite support rails 2 is two or more, the composite support rails 2 are arranged in parallel and evenly distributed; each composite support rail 2 is detachably provided with a plurality of composite frame photovoltaic modules, and the plurality of composite frame photovoltaic modules are arranged side by side along the length direction of the composite support rail 2, and a middle pressure block 5 is arranged between each two adjacent composite frame photovoltaic modules, and the middle pressure block 5 is used to press the two composite frame photovoltaic modules in contact with it onto the composite support rail 2.

[0028] Specifically, the composite material frame photovoltaic assembly includes a composite material assembly frame 1, in which a photovoltaic panel is installed; a medium pressure block 5 is arranged between two adjacent composite material assembly frames 1 on each composite material support rail 2, and the medium pressure block 5 is pressed against the upper surface of the composite material assembly frame 1, and at the same time, the medium pressure block 5 is pressed against the end face of the composite material assembly frame 1; at this time, the medium pressure block 5 can be detachably arranged on the composite material support rail 2.

[0029] At the same time, a side pressing block 4 is also arranged between the two composite component frames 1 near the two ends of each composite support rail 2 and the composite support rail 2, that is, Figure 1As shown, the edge pressing block 4 near the left end is used for pressing and fixing the composite material component frame 1 at the leftmost position, one side of the edge pressing block 4 is pressed against the upper surface of the composite material component frame 1, and another side of the edge pressing block 4 is pressed against the end face of the composite material component frame 1; similarly, the edge pressing block 4 near the right end is used for pressing and fixing the composite material component frame 1 at the rightmost position (omitted and not drawn in the figure).

[0030] The intermediate pressure block 5 is connected to the composite support rail 2 by a bolt and nut assembly, that is, the bolts penetrate the composite support rail 2 and the intermediate pressure block 5, and the nuts are fitted on the outside of the bolts, and one side of the nuts is pressed against the intermediate pressure block 5, so that the intermediate pressure block 5 can be pressed and fixed to the composite component frame 1.

[0031] The edge pressure block 4 is connected to the composite support rail 2 by a bolt and nut assembly, that is, the bolts penetrate the composite support rail 2 and the edge pressure block 4, and the nuts are fitted on the outside of the bolts, and one side of the nut is pressed against the edge pressure block 4, so that the edge pressure block 4 can be pressed and limited on the composite component frame 1 at the two end positions.

[0032] By providing the side pressing blocks 4 and the middle pressing blocks 5 , it is possible to stably press the multiple composite material component frames 1 on each composite material support rail 2 onto the composite material support rail 2 .

[0033] In addition, each composite material support rail 2 is connected to the color steel tile roof 6 through a plurality of composite material special clamps 3; the composite material support rail 2 is fixedly connected to the color steel tile roof 6, and the composite material support rail 2 is detachably connected to the composite material support rail 2; Figure 3 As shown, the composite material support rail 2 is connected to the composite material special clamp 3 through a bolt and nut assembly.

[0034] The composite material support rail 2, the composite material component frame 1, and the composite material special clamp 3 are made of composite material. The composite material has glass fiber as a reinforcing material and polyurethane resin as a matrix. The density of the composite material is lower than that of steel, so that the weight of each component structure of the photovoltaic system is lighter and the building where the photovoltaic power station is installed has a load advantage. The composite material has better strength than steel, making the entire roof photovoltaic system safer. At the same time, the composite material support rail 2, the composite material component frame 1, and the composite material special clamp 3 have better corrosion resistance, salt spray resistance, and UV resistance, and are suitable for photovoltaic power station projects in salt fields, seaside areas, and heavily polluted areas.

[0035] Since the middle pressure block 5 and the side pressure block 4 can be detachably mounted on the composite material support rail 2, and the composite material support rail 2 is also detachably connected to the composite material special clamp 3, it is convenient to quickly assemble the entire photovoltaic system, shorten the construction process, and facilitate maintenance.

[0036] Embodiment 2

[0037] See again Figure 1-Figure 5 This embodiment is based on the first embodiment. The composite material support rail 2 and the composite material component frame 1 are both made of insulating materials, so that the photovoltaic system does not need to use grounding materials for system grounding in actual use projects, which helps to reduce material usage and construction technology, reduces project costs, and speeds up the project construction process.

[0038] Embodiment 3

[0039] See again Figure 1-Figure 5 This embodiment is based on the second embodiment; since the color steel tile has a plurality of protrusions, a diamond-shaped protrusion structure is provided on the protrusion of the color steel tile; and as Figure 3 As shown, the special clamp 3 for composite materials consists of a left clamp plate 301 and a right clamp plate 302, which are connected by a bolt and nut assembly, and a slot adapted to the raised structure is formed between the left clamp plate 301 and the right clamp plate 302. By cooperating with the slot and the raised structure, the left clamp plate 301 and the right clamp plate 302 are simultaneously pressed onto the raised structure by the bolt and nut assembly, which facilitates the connection and fixation of the special clamp 3 for composite materials and the color steel tile roof 6, and realizes the detachable connection of the special clamp 3 for composite materials to the color steel tile.
